TAP AND BUSHING FOR BARRELS.

SPECIFICATION forming part of Letters Patent No. 409,288, dated August20, 1889.

Application filed March 9, 1887. Serial No. 230,172. (No model.)

To all whom it may concern:

Be it known that I, GEORGE XV. JACKSON, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Tap and Bushing forBarrels, of which the following is a specification.

My invention relates to improven'ients in taps and bushings for barrels,especially adapted for use in barrels containing beer, ale, and otherliquids, in which a bushing is inserted in the barrel and the tap isinserted in this bushing; and the objects of my improvement are, first,to provide an easy means for tapping barrels; second, to prevent leakageor the escape of the liquid while the barrel is tapping; third, toenable a single barrel to be more often refilled without repairing thehead or other part where the tap is inserted. I attain these objects bythe apparatus illustrated in the accompanying drawings, in which- Figure1 is a vertical sectional view of the barrel-head with the tap inserted.Fig. 2 is a side View of the bushing. Fig. 3 is an end view of thebushing, showing the inside end. Fig. at is a side view of the tap,showing the inside locking-joint, the cap to prevent escape of theliquid when tapping. Fig. 5 is a vertical sectional view of the tap,showing modifications by which the improved tap and bushing may be usedwhen the liquid is forced out under pressure through a pipe.

Similar letters refer to similar parts throughout the several views.

The bushing B, made of iron or other suitable material and threaded onthe outside, is screwed into the head of the barrel A, (which is alsothreaded,) and is flush, or nearly so, with the surface of the barrel.The interior of the bushing B is elliptical in cross-section, the lowerend of said interior being of less cross-section than the upper end, andfrom a point near the top of said bushing the interior surface is cutaway to a greater extent to the top of said bushing, thus forming theprojection a in the interior of the bushing. \Vhen the barrel is filled,a cork or bung of other suitable material is inserted in the bushing B.A portion of the inner end of the bushing B projects above the otherportion, forming a locking-joint G.

The tap O is made of brass, wood, or other suitable material, having, asin Fig. 1, a spigot M and turn-cock N.

The tap C is of such shape that it will pass through and turn in thebushing, and yet, as nearly as such conditions will allow, conform tothe interior of the bushing. The end of this tap has a projection F,which is of such shape that it conforms to the locking-joint G of thebushing. The projection F in cross-section is an ellipse, having itsmajor and minor axes of the same length as the major and minor axes ofthe cross-section of the interior of the bushing B. The tap 0, exceptthe projection F, is preferably cylindrical in shape, and therefore acircle in cross-section. The diameter of this circle is equal in lengthto the minor axis of the ellipse, which is the cross-section of theinterior of the bushing B.

V hen the tap O is inserted in the bushing B, the major and minor axesof the elliptical cross-section of the projection F, respectively,coincide with the major and minor axes of the elliptical cross-sectionof the interior of the bushing B. \Vhen the tap is inserted, the axes ofthe circular cross-section of cylindrical part of tap C coincide withthe major and minor axes of the elliptical crosssection of the interiorof the bushing B, the diameters of course being somewhat shorter thanthe major axis. When the tap O is inserted and turned in order to lockit, the major axis of the elliptical cross-section of the projection Fwill coincide with the minor axis of the elliptical cross-section of theinterior of the bushing B, and vice versa. At the projection a is awasher of leather or other suitable material. The collar H may be madewith a thread inside, and may be screwed up in order to fix the tap morefirmly in the bushing, or may be made rigid with the tap.

In Fig. 1 the end 7c of the tap is solid and the liquid flows out thespigot M, and its how is regulated by means of the stop-cock N.

The cap D (shown in Fig. 4) is made of rubshoulder a in said bushing, alocking-joint G her or other suitable material, and its use pi'eat theend of said bushing, a tap O, a projec- 1o vents the liquid from leaking0r Spurting out tion F on said tap, a collar H, and a cap D. when thetap is inserted.

5 Having now fully described my invention, GEORGE W. JACKSON.

What I claim, and desire to protect by Letters WVitnesses: Patent, is-RICHD. S. CHILI), J 1:,

In combination, a bushing B, an internal BUTLER KENNER HARDING.
